This is the new top flake, the "https" one. Over a hundred of these in the last week:

@giuseppe PTAL

           Expected
               <string>: time="2021-06-09T10:05:50-05:00" level=warning msg="Cannot move process 533368 to cgroup \"/sys/fs/cgroup/user.slice/user-12955.slice/[email protected]/user.slice/podman-pause.scope\""
           to be empty

I think we should ignore the warning, or downgrade it to a debugging message

[giuseppe]

The failure seems to happen reliably with updated images, so added a patch here: #10451
